Guildfordia

Guildfordia is a genus of sea snails, marine gastropod mollusks in the family Turbinidae, the turban snails.

Description

The imperforate shell is wheel-shaped. It is low-conic and granulose above, convex below. The periphery is armed with long slender radiating spines, which are concealed at the sutures. The operculum is flat, with a subobsolete arcuate rib outside. The central tooth of the radula has no cusps.
